Among the objects of the present invention, it is aimed to provide an improved stock quotation projecting machine in which there is provided a tape pulling roller including a continuously operating motor and a device for disconnecting the driving relation of the tape pulling roller with the motor in cooperation with a tape anchoring means at the light aperture which will preserve the tape smooth at the light aperture both when thetape is being drawn by the tape pulling roller and when the tape pulling roller is at rest.

These and other features, capabilities and advantages of the present invention will appear from the subioined-detail description of specific embodiments thereof-illustrated in the accompanying drawingsin which Figure l is afront elevation of a stock quotation projecting machine made according to the present invention;

Fig. 7 is a fragmental section on the line 1-4 of Fig. 6. v

In the embodiment shown in Figs. 1, 2, and 3, the tape I is intermittently discharged by the ticker 2 and from it passes under the roller 3 journaled in the bracket 4 on the side of the extension 5 of the lamp housing ll. After passing under the finger 3, the tape l passes over the light aperture formed at the upper end of the extension 5 and then passes down under the tape pulling roller 6 journaled in the sleeve 1 pivotally mounted at 8 in the bearings 9 secured to the front of the housing ll.

From the tape pulling roller 6, the tape passes up into engagement with one side of the finger H at the lower end of the arm I! pivotally connected to the upper end of the arm l3 extending from the upper end of the sleeve l4 formed in the extension I5 extending upwardly from the housing It. From the finger H, the tape passes to the mandrel of the rewind reel l8.

At the entrance end of the light aperture, there is formed an opening ll at one end of the branch conduit it connected at its lower end with the main conduit I9 connected to the fan or blower inside of the casing 20. At the discharge end of the light aperture, there is formed the opening 2] at the upper end of the branch conduit 22 which likewise is connected to the. upper end of the main conduit is. The blower or fan in the casing 20 is mounted on the shaft 28 on which is fixed a sheave 24 connected by the spring belt 25 with the sheave 28 on the shaft of the motor 21. The shaft 23 extends into the housing I 5 and has fixed thereon the worm 28 in mesh with the worm wheel 29 'on the shaft 30. The shaft 30, see Fig. 3, has a gear 3| thereon in position to mesh with the gear 32 on the shaft of the pulling roller 8 Journalled in the sleeve I when the pulling roller 8 is disposed in its descended or tape pulling position.

For normally urging the tape pulling roller into tape pulling position and therewith the gear 32 to mesh with the gear 3|, there is provided the spring 33 connecting the abutment 34 on the end of the shaft of the tape pulling roller 8 with the abutment 35 extending from the lower end of the housing l0.

For maintaining the tape in pulling engage ,ao ment with the pulling roller 8. there is provided the friction roller 36 journaled on the end of the long arm 31 of a bell crank pivoted at 38 to the front face of the housing l0 and having a short arm 39 connected by the spring 40 to the abutment 4| extending from the front face of the housing ill.

The shaft 30 has alsofixed thereon the sheave 42 connected by the spring belt 43 with the sheave 44 fixed on the shaft of the rewind reel It. The shaft of the rewind reel It has a brake drum 45 fixed thereon to be engaged by the brake shoe 46 on the arm l2.

The operation of the embodiment just described is substantially as follows: The fan in the casing will be continuously actuated to effect a drawing action on the tape at the openings l1 and 2| to cause the tape both at the entrance and discharge ends of thelight aperture to hug the abutments at such ends, there to iron out any vibrations that may be transmitted to the tape I either by the ticker 2 or by the pulling force exercised on the same by the tape pulling roller 6. Furthermore, it will be noted that when the ticker stops and the tape pulling roller 6 comes to rest the drawing action exercised on the tape by the air at the opening 2| will lock the tape l against displacement by the tape pulling roller 6, the sucking or drawing force of the air at the opening 2| being so predetermined that it will be sutllcient to anchor the tape l against displacement when the tape pulling roller 6 comes to rest but not sufiicientto interfere with the tape pulling action of the tape pulling roller 6 when the roller 6 is operating to draw the tape l across the light aperture.

It will also appear from the foregoing that when the ticker stops and the tape continues to be drawn by the roller 8 and rewind reel l8, it will initially takeup the slack in the tape bego tween the ticker and the tape pulling roller 6 and then draw the tape pulling roller 6 upward about the pivot pin 8-in turn to clear the gear 32 from engagement with the gear 3|.

Preferably the teeth of the gears 32 and 3| will be very shallow ordinarily just sufllcient to cause a frictional driving engagement between the two. Furthermore, the arm of the shaft on which the pulling roller 6 is fixed is shorter than the arm on which the gear 32 is fixed so that a small movement upward of the pulling roller 6 will be sufllcient to cause the gear 32 to clear the gear 3|. The tension in the tape I thereafter continues to pull the finger II inward in turn to press the brake shoe 46 into engagement with the brake drum and thereby lock the rewind reel I6 against rotation and cause the spring belt 43 to slip relative to the sheave 44.

The position of the friction roller 36 is such that when the tension in the tape I is relieved, the spring 33 will cause the tape I on the tape pulling roller 6 to be pressed into driving engagement with the roller 36. It will also appear that the stop 41 will limit the upward movement of the arm 31 with the spring 40 when the pulling roller 6 is drawn upward by the tension in the tape I so that. the tape pulling roller 6 may efiectively clear the roller 36 when the ticker'comes to rest and the tension in the tape I is increased sufficiently to draw the roller 6 upward into arresting position.

In the embodiment illustrated in Figs. 4 and 5, the tape pulling roller 48 used in place of the tape pulling roller 6 illustrated in the embodiment shown in Fig. 1, is here journaled at the end of the arm 48 of a bell crank pivotally mounted at 50 to the outer face of the gear casing 5|. The other arm 52 of such bell crank has a locating pin 53 secured to its outer end for a compression spring 56, said spring abutting against an adjustable screw stop 55 in the abutment 54. The spring 56 normally urges the arm 52 outwardly to press the gears 58 and into mesh and the roller 48 down into contact with the friction roller 51. The tape pulling roller 48 in the present instance is fixed to a shaft 58 journaled in the end of the long arm 49 which shaft in turn has secured to it at its inner end a gear 59 having shallow teeth to engage and mesh with the teeth of the gear 60 fixed on the shaft 6|, and drivingly connected to the motor 62 in the same way that the shaft 'Iis drivingly connected to the motor 21. Here with this embodiment when the ticker stops and the tension is increased in the tape 62, the tape pulling roller 48 and gear 58 will rock about the pivot point 58 to clear the gear 60 and friction roller 51.

In the embodiment illustrated in Figs. 6 and 7, the tape pulling roller 63 used in place of the tape pulling roller 6 of the embodiment illustrated in Fig. 1 is fixed to a shaft 64 journaled in the end of the arm 65 pivotally conected at 66 to the outer face of the casing 61. The shaft 64 has fixed thereon the sheave 68 which is connected by the spring belt 69 with the sheave 10 on the shaft II of the gear I2 drivingly connectedto the electric motor not shown in the same way that the gear 3I is drivingly connected to the motor 21 of the embodiment shown in Fig. 1.

The arm 65 is provided with a spring I3 toeffective driving relation to one another. With this embodiment when the ticker stops,and the tension in the tape 14 is sufllciently increased, it will raise the tape pulling roller 63 and the sheave 68 to rock about the pivot point 66 thereby to bring the tape pulling roller 63 out of drivingrelation with the friction roller 15 and the sheave 63 out of driven relation with the sheave 61.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.
